The synthesis and structure elucidation of three new chiral xanthone (9H-xanthon-9-one) derivatives (2–4) are fully reported. The coupling reactions of the synthesized building block 6-methoxy-9-oxo-9H-xanthene-2-carboxylic acid (1) with two enantiomericallypureamino alcohols ((S)-(+)-valinol and (S)-(+)-leucinol) and one amine ((S)-(−)-α-4-dimethylbenzylamine), were carried out using the coupling

specific leukotriene B4 (LTB4) receptor antagonists, several xanthone dicarboxylicacids were synthesized and evaluated. Two separate synthetic routes were used to construct a xanthone nucleus containing a regiospecific orientation of each carboxylic acid pharmacophore. These compounds represent the major conformationally-restricted analogues of benzophenone dicarboxylicacids previously shown to antagonize
